Google founders Larry Page and Sergey Brin collectively own 57,806,476 shares of Google stock. One month ago, Google's stock was trading at $710.84 — putting Larry and Sergey's combined holdings at $41.1 billion. That'll buy you a few party planes, right? Not so fast. In the past month, Google's stock has fallen almost every day, with the biggest drop coming today. The one-day loss for Larry and Sergey? Almost $2.5 billion, bringing their total losses to $10 billion in just under a month. I guess I won't complain about the $120 I lost at the poker tables with Jason Calacanis last month.
